Application filed August 4, 1910, Serial No. 575,428. Renewed. May 4,1912. Serial No. 695,323.

To all whom t may concern:

Be it known that I, CHARLES RosANZ, a citizen of the United States, anda resident of the city of New York, borough of Brooklyn, in the countyof Kings and State of New York, have invented a new and ImprovedGas-Generator, of which the following is a full, clear, and exactdescription.

This invention relates to a new and improved apparatus for generatinggas from a suitable chemical by the contact therewith of a suitableiiuid or liquid.

An object of this invention is to provide a device which will be simplein construction, inexpensive to manufacture, strong, durable, andreasily regulated, y

A further object of this invent-ion is to provide a device in which vtheamount of gas generated is automatically regulated by the pressure ofthe gas generated. I

These and further objects, together with the construction andcombinat-ion of parts, will be more fully described hereinafter andparticularly set forth in At-he claims. y

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar' characters of reference indicatecorresponding parts in both views, and in which Figure 1 is a verticalsection; and Fig. v2 is a horizontal section on the line 2 2 of Fig. l.

Referring more particularly to the separate parts of the device,l'indicates a suitable receptacle, in the form of a tank, which ispreferably provided with a main bottom 2 and a false bottom 3 spacedapart from the main bottom 2 a suiiicient distance to form a chamber 4,which may be termed the gas storing chamber. Above the false bottom 3,the tank 1 is adapted to hold the fluid, such as water, which is to acton the chemical from which the gas is generated. For the purpose ofsupporting the chemical in the tank 1, there is provided a holder 5,which may be of any suitable character, such as a wire basket,`but isshown in this case in the form of a tubular rod or pipe which extendsdown through the false bottom 3 into the chamber 4, where it is providedwith outlet openings.

On the pipe 5, there is provided a support, in the form of a disk stand6, on which is adapted to rest the chemical to be utilized in formingthe gas, which in this instance is shown in the form of cylinders 7having central openings therein, whereby they are adapted to be slidover the pipe 5 and supported by the stand6.

For the purpose of inclosing the holder 5 and the chemical 7carriedthereby, there is provided a cap 8, which' is in the form of adome 9 having a vertical extension 10y connected thereto, of somewhatsmaller diameter. The cap 8 is provided adjacent its lower end with aplurality of inlet openings 11, through which the fluid in the tank 1can enter the lower and upper chambers provided by the dome9 and theextension 10. The fluid, such as water, which comes in contact with thechemical 7, such as calcium carbid, generates the gas Vin the chamberformed in the extension 10, and this gas can enter the pipe 5 throughanopening in the top thereof, from whence it passes down into the chamber4. From the chamber 4 this gas can be drawn to the point whereit isdesired to utilize it,'through a suitable connection 12, controlled by avalve 13. The chamber 4 is kept partially full of water to wash the gasas it comes therein. The amount of this water is gaged by leaving a.pet-cock 14 open until the water starts to come out, when the supply canbe shut off. This water can be supplied to the chamber 4 either throughthe pipe 5, when the cap is removed, or through the pipe 12, or in anyother suitable manner. l

For the purpose of covering and protect-v ing the liquid in the tank 1,there is provided a floating cover plate 15, which has a central opening16, whereby it can be slidingly mounted on the extension 10, and isfurther provided with a plurality of perforations 19, permitting thetransudation of any excess liquid.I This cover plate 1 5 may be lockedin position by means of lugs 17 on the tank 1l The cover plate 15 isprovided with openings 18, whereby it may be passed beyond the lugs 17and secured beneath the same by giving it a partial turn.

The operation of the device will be readily understood when taken inconnection with the above description. A suitable number of cakes orblocks of thechemical 7 are supported by the holder 5, and the cap 8placed thereover, and a suitable liquid supplied to the tank 1. As soonas the liquid enters the openings formed in the cap 8, and comes incontact with the chemical 7, a gas will be generated, which willgradually force the level of the liquid within the cap 8, down,

and this gas will pass through the pipe 5 into the chamber 4. If thevalve 13 is open, and the gas is being utilized through'the connection12, it will continue to generate in the cap 8 as fast as needed. If,however, the valve 13 should be shut oli", -then the gas will graduallyaccumulate in the extension chamber 10, and thereby force down the levelof the liquid within the cap 8 until the top surface thereof is out ofcontact with the lowermo-st block of the chemical 7 so that no more gaswill be generated. As soo-n as the gas is utilized by opening the valve13, the pressure within the extension chamber 10 will be decreased andthus permit the level of the liquid within the cap 8 to rise, permittingthis liquid to come in contact with the chemical, thereby generatingmore gas. Inasmuch as the chemical is arranged in a vertical series ofblocks, any diminution of the pressure within the cap v8 will permit theliquid level to rise within the cap 8, so that a greater amount of thechemical will be in Contact with the liquid, thereby generating agreater amount of gas. It will be seen that this. arrangementautomatically regulates the amount of gas generated, according to theneed thereof. As the lower blocks of the chemical are used up, the upperblocks will sink down to take their place, so that the generator can runa long time with a single filling.

While I have shown one embodiment of my invention, I do not wish to belimited to the specic details thereof, but desire to be protectedinvarious changes, modifications and alterations which may come withinthe scope of the appended claims.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a gas generator, the combination with a tankhaving a bottom, of a false bottom in said tank spaced apart from saidfirst-mentioned bottom to form a storing chamber, a pipe extending insaid chamber and having a communicating opening therein letting intosaid chamber and also extending above said false bottom to form a holderadapted to receive blocks of chemical having openings therein, and a capin said tank adapted to cover said chemical and having an extensionlportion forming a chamber around the chemical on said holder, said pipehaving an opening in the top thereof, whereby gas generated from saidchemical may pass into said storing chamber.
